1. What Is Refillable Packaging and Why Do Brands Need It?

Traditional single-use containers generate large amounts of plastic waste, especially in skincare and personal care categories. Refillable packaging offers a simple yet transformative shift. A durable outer container is reused, while only the lightweight inner component is replaced. This system reduces overall plastic consumption, encourages long-term use, and helps brands communicate genuine environmental responsibility.

2. COSJAR’s Refillable System: How PP Inner Refills Reduce Waste

COSJAR’s refillable packaging consists of two components:

✔ A reusable outer bottle or outer jar

Made of PMMA, PETG, or PET, these containers are durable, visually luxurious, and built to last—minimizing the need for full replacement.

✔ A lightweight PP inner refill

Our refill cups and inner bottles are 100% PP (polypropylene), a mono-material that improves recyclability and reduces environmental impact. Because the refill uses far less plastic than a complete container, switching to refillable packaging can cut plastic waste dramatically:

A 50ml refillable jar can reduce plastic consumption by approximately 60–75% annually,

depending on consumer refill frequency. This plastic reduction also translates directly to carbon footprint reduction across manufacturing and transportation.

3. Versatile Options for All Skincare Formulas

Our refillable packaging portfolio covers a wide range of capacities and formats, suitable for modern beauty routines.

Refillable Bottles

Ideal for serums, emulsions, lotions, and toners: 20ml/ 30ml/ 50ml, compatible with lotion pumps, spray pumps, or droppers.

Refillable Jars

Perfect for creams, balms, and rich skincare formulas: 30ml/ 50ml, all products support full customization—coloring, matte or glossy finishes, hot stamping, gradient spray, and brand logo decoration.

4. Meeting EU PPWR Requirements with Refillable Packaging

The EU Packaging and Packaging Waste Regulation (PPWR) is set to become the most influential sustainability law impacting the beauty sector. Its goals include:

- Reducing single-use plastics

- Increasing reusable and refillable packaging usage

- Lowering total packaging waste

- Improving recyclability through mono-material design

COSJAR’s refillable packaging system was developed with these principles in mind.

How COSJAR Helps Brands Comply with PPWR:

a. Supports Reuse Targets

The outer container can be reused repeatedly, aligning with PPWR’s emphasis on extending packaging lifespan.

b. Reduces Plastic Consumption

Lightweight PP refills help brands meet reduction targets for virgin plastics.

c. Improves Recyclability

Because COSJAR uses PP mono-material refills, they align with PPWR’s push toward simplified, recyclable packaging structures.

d. Future-Proof Sustainability Strategy

By adopting refillable packaging now, brands can prepare for PPWR compliance and strengthen their competitive edge in European markets.

5. The Business Benefits of Switching to Refillable Packaging

Choosing refillable packaging offers advantages far beyond sustainability:

Clear Plastic Waste Reduction

Ideal for ESG reporting and sustainability claims.

Lower Carbon Footprint

Less material → Lower production emissions → Reduced transport impact.

Higher Consumer Loyalty and Refill Purchases
